A9r Claims. l

This invention relates to improvements in a device for turning and labeling bags.

The present invention contemplates the provision of a machine operable to pneumatically turn a bag of fabric material right side out, and then to automatically apply a label to the face thereof preparatory to lling. 'i

Thefprincipal object of this invention is the provision of a pair of cylindrical drums rotatably mounted in parallel relation, and adapted to have a partial vacuum formed therein, whereby wheny an inlet valve formed in the periphery of one .of said drums is opened in communication with a chute to which is attachedthe open mouth of a bag, said bag will` be turned right side out as it isv drawn into said tube, whereit will be engaged by grippers carried by said drum and secured yto rotate with the drum. Y l

` Another object of the present inventionis the provision of a labeling drum adapted` to pneumatically support a label on its periphery as it is .coated with an adhesive and applied` to a. bag

carried by a rotating drum disposed in operbags made of substantially any size and `from any type of fabric material. Y

With these objects in view as well as other objectsj which will appear during the course of thelspeciiication, reference will be had to the drawings, wherein: 1

Throughout' the several views like reference numerals refer to similarparts and the numeral 26 designates a frame having side standards 22 and 24 joined together adjacent their lower portions by means of transverse end bars 26.

Standard 22 has a substantially closed facev28 upon Whichcertain of the driving parts are attached as hereinafter set forth. The other standard 24 which is on the bag delivery side of the machine is open at 30 and is provided adjacent its base with a crossbar 32 whereby the legs 34 are reinforced. Mounted in face plate 28 is a bar 36 which` extends between the standards and into the opening `3l) whereby bags B delivered to bar 36 may be manually removed through opening .30 from the machine. Secured to the lower edge of face plate 28 and extending outwardly from the frame 26 is a horizontally disposed shelf 38, having a vertically extending post 40 provided vwith a foot 42 adapted to rest on the oor and an upper portion 44 vadapted to provide` a bearing-as hereinafter set forth.

A bag carrying drum 46 and a label carrying drum 48 are rotatably mounted in frame 20 with their axes in parallel relation. Drum 46 is provided at its one end with stub axle 50 rigidly se'- cured in axial relation to the drum. .This axle is mounted in a bearing 52 formed in thevupper surface of standard 24 and having a removable cap 54. The other end of drum 46 is providedwith an enlarged hollow axle 56 which is rigidly secured thereto in axial alignment with axle 50. This axle is rotatably mounted in a bearing 68 formedV in the upper portion of standard 22 which is yprovided 'with a removablecap 60j.' The outer end of hollow axle 56 is provided withl an outwardly projecting annular flange '62 which serves to form a substantially airtight joint with an inturned annular grooved end `portion 64of a tubular inlet pipe 66 of a vacuum pump housing 68er a vacuum pump'lll. This pump isprovided with a rotatable axlez12 on which is vnioun'ted'the propeller blades 14. This axle extends outwardly.`

3 to bear in the upper end portion 44 of post 40, and is provided intermediate post 40 and pump housing 68 with a sheave wheel 76 which is adapted to operatively receive a belt 18, driven byrsheave wheel '|53 actuated by motor 80 which is mounted on shelf. 38. VAs the suction pump is Yoperated air is drawn from drum 46 thus creating a partial vacuum therein, and delivering the exhaust air through the exhaust port 82 to any v desired point.

Removably mounted on the upper surfaces oi'l standards 22 and 24 is a pairvof likebridge mem-i Vbers 84 and 86 respectively securedinposition screws .90.to standards 20 andfZZ-z. f

Referring to Figs. 3 and 4, it will be notedthat members 84 and 86 are joined together by a' .one end of the lips IUS-or |08, pulls the bag to extend spring |3| andhooks the other side of the bag over the other lip so that the bag is held `undertensionztightlyabout the mouthpiece with v the openend of tube |00 otherwise closed.

VReferringfnowto .bag .drum |356,` reference will be had to Figs. .6; 8 and l1'3'.which.show the parts in their relative positions just after the turned closed end of the bag has been gripped.

The bag gripping. means |68ispositioned below the periphery. of the drum. and comprises: a. rodv |62 rotatably mounted'in'the radial Walls-.ofsaid drum to rest in a recess |64, formed in the-peripheryof-the drum, inparallel relationbwith Vthe axi'sof'lsaid d'rlum.- Thisrod `isvprovi'ded with a,v seriesfof bag gripping ftongues |66 spaced be tween guard members'zlE-:whicliserve toprevent the bag from interferingi w1 ationoftongues-IGS.

:the-proper .oper-f ingl |85 .where it may be engaged by tongues |66, as the vdrum 641s rotated,ingananti-clockwisedirection, as; indicated by the arrow, when stationaryy pin |86 carried bybridgefmember 84 .engages operating arm |1| to move it from its position lon section |80 of spring I 12l over the humpl end onto the oppositely inclinedsection |18 of said spring detent. These tongues will remain in the gripping position until drum 46;has rof tated to a-position where stationary detent |88 will engage lug I 90 integral with arm l|10, to

move said arm so as to againpsitionsaid arm against section |80 of spring "l1 2 thussecuring the tongues |66 in the openpositi`on in recessv |64. This operation of the gripping means is repeated at each revolution of the drum.

Just in front of recessv |64`is'formed va wallv |92 protected by peripheral strips |94. Wallv 92 is4A from 'their' seats'to open the inlet valv'eto'the interior of drum 46 from which most-of the vair hasbeen pumped. It will be noted that. valve member 202. is considerably larger in area than valve member 204, thus insuring the maintain' ing of the valve in the closed Iposition solong'a's the pressure outside the drum chambery is greater than the pressurewithin said drum chamber'. A spring detent 206 mounted on the endl41 of drum 46 by means of pins208 and 2I0"serve'to. bear against the lever arm 2|2 rigidly'mounte'd'on' the extended end of rod ,200 to maintain the valve in either the open or closed position. This spring detent 206 has a pair of oppositely disposed inclined surfaces v2| 4 and 2|6. As clearly shown in Fig. 8 when lever 2|2rests. against spring portion 2|4 the Valve will be held in the o penposition to allow air to enter into the cham;- ber of drum 46 thus drawing the bag B into chute 92 and in position for gripping by means of tongues |66. The valve .isopened by means of stationary detent 2|8 striking lever 2|2 asthe drum is rotated. Since this yalveneeds to be opened only. for a shortperiod of` time, an adjustable pin 2mv carried by bridge =member'at engages lever arm 220 to close the Valve with operating arm 2 I2 restingon the inclined portion 2|6 of detent spring 2v08. A l

To permit free movement of the bagnpast the endvof chute 92, it ywill be noted that the top vof the portion of the chute is spaced apart fromv theperiphery of drum 46l at 222, however, thisl opening is normally closed by a roller 224 lhaving an axial pin 226. The roller 224 ishinged to chute member 92 by means of links 228. This roller raises as the sack passes thereunder and then drops down again to close the gap. .A series of holes 230 formed'concentric about the axis of drum 46 serve to receive pin |88 to permit the proper spacing `o1 vthe release of gripping A tongues |66; Also a series of holes 232 allow forpositioning the closing pin 2|9 for the valve 202.

Referring now to label drum 48, it willbe noted that the drum is slightly less in diameter than drum 46, has a peripheral plate 234 of uniform thickness and is secured 'in position by screws 236. This plate is of suitable size to support a rectangular label 238 that is fed thereon'by yhand as hereinafter setforth. Plate 234 is slotted at 240 to form a suitable grill 242v which conirnuni-` cat es with va well 244l foi-medi inwardlmfromgth periphery ofdrum 48 by substantiallygradially1- disposed walls 2464 which carryat their inner,- edges valve seats-,248 and 250.;` A valve rod 252.-. mounted for rotation inthe end walls of,dru m 48 carries-valve.nf1embers254` and 25,6. 1

These valve members'are positioned relative-toi, the seats; 2.48 and 250V soxthjat when the drum.;is` rotated in the direction. indicatedgby the arrow- (see Fig. 8) they will moveto. andgfrom thecompletely-closed position. Thismoving. offthegvalve members is accomplishedby means-.of -azleyer arm 258 rigidly secured intermediateitsends. to, the endof valverod. 252 `whiehextends outwardly.:

It will be noted that detent spring 264 is 'securedin position by means of p ins 266 and` 268 mounted in end plate 210 of drum 48. Normally the valve members 254 and 256 are held in sealed position againstthevalve seats ybythe greaterair pressurev outside A`the. drum resting,v

Thev label drum48 is provided at its one end with an axle member 284 mounted in adjustable bearing block 286 whichis'slidably mountedcin bearing'v288 carried by -standard '24. Adjusting screws 290 mounted in bearing288 are operable to vary the distancebetween drums 46 and 48; and `springs y292 mounted in bearing'288 to bear againstV block 286 constantly urge the block against screws 290, however,v when sacks of greater thickness pass between the drumsthe springs will permit them to separate suicie'ntly to lcompensatetherefor'. The otherend of drum 48 lis providedy with a hollow axle 294 Vwhich isrigidly secured-thereto in axial alignment with axle 284. This axle is rotatably mounted in a bearing block 296 which is slidably mountedy in a bearing 288 provided with adjusting screws and spring'similar to thebearing for axle4 284, to compensate for the movement of bags of ldifferent thicknesses passing between the drums.
